MAGAZINE PLATE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 631,249, dated August 1 5, 1899.

Application filed October 25 189 8.

To all whom it may concern:

Be it known that 1, WILLIAM F. FOLMER, of the city of New York, borough of Brooklyn,

' in the county of Kings and State of New York,

have invented certain new and useful Improvements in Magazine Plate-Holders for Photographic Cameras, of which the following is a full, clear, and exact description.

The object of the invention is to provide a :0 new and improved magazine plate-holder for convenient attachment to and removal from a photographic camera and arranged to permit the operator to make the desired exposure in the usual manner upon removing the slide,

to remove the exposed plate or film and store it in the back of the holder, and at the same time automatically bring an unexposed plate or film into position for exposure, the various changes mentioned being possible in broad 2o daylight without a dark room or the like and without danger of the plates or films becoming light-struck.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a perspective view of the improvement with the slide partly withdrawn. Fig. 2 is an enlarged front elevation of the improvement with parts broken out and the exposed plate partly withdrawn from the front opening of the holder. Fig. 3 is a sectional plan View of the same on the line 3 3 in Fig. 2. Fig. 4 is a sectional plan View of part of a plate-holder on the line 4: 4 of Fig. 13. Fig. 5 is a sectional plan view of the improvement with parts in a different position from that shown in Fig. 3. Fig. 6 is a sectional front elevation of part of the improvement, show ing the locking device for the slide and the holder in position on the camera.

position. Fig. 10 is a sectional plan View of a modified form of the improvement arranged for the use of films. Fig. 11 is a perspective View of the reducing-plate employed when using films. Fig. 12 is a cross-section of one of the plate-holders, and Fig. 13 is a rear face view of the same with parts broken out.

Theimproved magazine plate-holder is provided with a box A, preferably made rectangular and lined with sheet metal, to contain a number of plate or film holders B, located in front of one another, a slide 0 being movably held in the apertured front A of the box to allow of making an exposure when desired upon withdrawing the slide, it being understood that the sensitive plate or film in the front holderv B is the one exposed to the light passing through the lens of the camera. The side A of the box A is out out or formed with two vertically-disposed slots A A of which the slot A is adjacent to the front A, and through said slot the front plate-holder, with the exposed plate, is removed, as hereinafter more fully described, and through the rear slot A the removed and exposed plate-holder is passed back into the casing at the rear or back end thereof, as will be readily understood by reference to Fig. 5.

On the box A, at the side A is arranged a bag I), the month of which is attached to this end of the box, so that the exposed plate during the transfer from the front to the rear passes into said bag and is taken hold of 8 5 therein by the operator, as indicated in Fig.

5, to shift the plate back into the casing at the rear end thereof. The several plate-holders are always pushed forward to bring the front plate-holder into proper position for exposure, a spring E being preferably provided for this purpose to press against the rear plate-holder in the box, said spring being secured to the inner face of the back A of the box.

The side A" terminates a short distance from the ends of the front A, the back A the top A, and the bottom A so as to form a place A adjacent to the back for guiding the inner free end of the removed plate-holder IOO while in the bag and du ring the transfer from the front to a rearmost position in the box. The side A is also out out at its rear edge and near the middle thereof, as at A, (see Figs. 5

and 8,) to permit the operator to readily push the plate-holder home into proper position in the back of the box.

In order to move the front plate-holder after exposure out of the box through the slot A into the bag D, I provide a bar F, fitted to slide in suitable hearings in the bottom A the bar having a lug F atits rear end for engaging the side edge of the front plate-holder B adjacent to the side A of the box to permit the operator upon pulling the bar outward to draw the front plate-holder along, as

will be readily understood by reference to Figs. 2 and 3. The bar F extends to the outside of the box at the side A and is formed at its end with a pull F adapted to be taken hold of by the operators fingers, to move said bar outward to push the front plate-holder into the bag, as before mentioned. When the plate-holder has passed into the bag, the operator, on taking hold of the outer end of the bag at opposite sides thereof, can readily engage the edge of the plate-holder and pull the latter completely out of the front of the casing upon stretching the bag to its fullest extent, and while the operator has hold of the plate-holder in the manner described he can readily swing the plate-holder rearwardly to bring the front end of the plate'holder in alinement with the slot A and then push the plate-holder inward by clasping the bag correspondingly and pushing the plate-holder home under the spring E. .Vhen the operator releases the pull F of the bar F, then a band or cord G, connected with said plate-holder close to the lug F, automatically returns said bar to its normal position, said band or cord G being connected with and winding on a spring-pressed shaft G, contained in a casing G attached to the bottom A of the box A close to the side A (See Fig. 7.) It is understood that the casing G2 has an opening in its rim for the passage of the band orcord G to and from the casing. 011 drawing the bar F outward the band G unwinds and winds up the spring connected with the shaft G, so that when the operator releases the bar the said shaft is rotated in the opposite direction by the force of the spring, and consequently the band G is wound up and the bar F is drawn back to an innermost position. The lug F normally extends in a recess cut in the side A (see Fig.7) to permit theplate-holders to move forward, the front plate-holder being in alinement with the lug F, so that on the next pulling out of the bar F this front plateholder is pushed through the slot A into the bag D, as previously described.

The outer end of the bag D is lined'at the inside with two vertically-disposed and oppo sitely-arranged stiffening-plates D to permit the operator to securely take hold of the plate upon pressing the outside of the bag, as will be readily understood by reference to Fig. 5. The mouth of the bag has the rear side, the top, and the bottom rigidly secured to the corresponding parts of the box A, but the front of the bag is secured in the doubled-up portion H ofa metallic plate ll, extending in the rear of the solid portion A of the front A, said plate ll being formed at the top and bottom with arms H fitted to slide in suitable guideways formed on the inside of the top A" and the bottom A (See Fig. 8.) The inner end of the plate H is covered in front of the doubled-up portion H with a strip H of felt or other soft material, either on the inner face of the slide 0 or the inner face of the solid portion A of the front A. (See Figs. 9, 3, 5, and 6.) The plate H is pressed on by a spring I, held in a recess in the side A as is plainly shown in Figs. 8 and 9, the front bent ends I of said spring resting against the plate at the inside thereof adjacent to the guide-arms 1P.

Now when the slide 0 closes the apertured front A of the box, as shown in Fig. 9, then the felt strip ll rests on the inner face of the slide, and the inner edge of the metallic plate H extends in the slot A so as to reduce the size thereof to such an extent as to be less in width than the thickness of a plate-holderll, and consequently the front plate-holder cannot be pushed through the slot A as long as the slide 0 is in the position mentioned and holds the plate H in the position stated. hen the slide C is withdrawn for making an exposure, then the spring I in pressing on the metallic plate H forces the same forward in the slot A until the strip H is firmly seated on the solid portion A of the front A. As the plate H moves outward in the slot A the latter becomes sufficiently large for the passage of the front plate-holder B, which can after exposure be pushed outward upon the operator manipulating the bar F, as previously described, the top and bottom edges of the plate-holder passing over guide-arms J, extending into the slot A at the top and bottom thereof, said guide-arms being securely fastened to the top A and bottom A of the box A.

The metallic lining K for the box is extended, as at K, over the rear edge of the side A as is plainly indicated in Figs. 6, 7, and S, and this edge of the end is preferably beveled to permit the removed and exposed plateholder to readily pass up to and through the slot A" into the back of the box.

hen films are used instead of the usual glass plates and the holders are correspondingly less in thickness, then it is necessary to reduce the width of the slots A A correspondingly, and for this purpose a metallic plate L is employed and slipped over thelin ing at the side A as is plainly shown in Fig. 10, said metallic plate L being provided at the front and rear with flanges L and L of which the flange L is beveled and fits over the beveled portion K of the lining. The other flange L extends into the slot A in the rear of the forward end of the metallic plate H. Now by the arrangement described the film-plate holder in the front of thebox canthe original last plate-l1 older becomes the front plate-holder, then the operator cannot push this plate-holder by the bar F through the slot A as the latter is less in width than the thickness of said holder, and consequently the operator becomes aware that all the plates have been exposed and a reexposure is completely prevented.

In order to prevent the slide 0 from being accidentally drawn out while the holder is not attached to the camera, I provide a locking device for the slide. (See Figs. 1, 2, and 6.) This locking device consists of a locking-lever N, arranged within a recess in the top A of the box, and said lever is fulcrumed at N and has one end formed with a catch N adapted to engage a notch (Pin the upper edge of the slide C. The other end of the leverN is pressed on by a spring N secured to the top A of the box, extending with its free end somewhat above the top surface of said top. (See Figs. 1 and 2.) The spring N normally permits the lever N to engage with its catch N the notch C in the slide to lock the latter against removal; but when the box A is placed in position on the camera 0 in the usual manner and locked thereto then the spring N is pressed inward by coming in contact with the framework of the camera, (see Fig. (3,) and consequently the said spring imparts a swinging motion to the lever N to move the catch N out of engagement with the notch 0 Thus when the box A is in position 011 the camera the slide 0 can be withdrawn, but when the box is remOvedfrom the camera and the slide is pushed into an innermost position then the spring being released causes the lever to swing to move upward the catch N in engagement with the notch C A portion A of the back A of the casing A is preferably removable to permit of conveniently filling and emptying the box with plate-holders, said removable portion being normally locked in place by a bolt P, (see Fig. 7,) adapted to engage a keeper P, formed on the side A of the box, and said bolt is normally locked in place when engaging said keeper by a spring P held, with the bolt, in a recess in the removable part. Now when it is desired to remove this part of the back .A the latter is slipped longitudinally to disengage the keeper P. The box can now be opened from the back by removing this part of the back for. the purpose men tioned.

Each plate-holder B is formed in its back with a depressed portion B, adapted to contain on its outer face a numeral or other character for distinguishing the plate-holders, the depression preventing the character from being scratched or injured in the changing of theholders. The depressed portion B is adapted to engage the clean face of the sensitive plate or film, as is plainly shown in Fig. 12, to securely bring the plate or film into the focal plane against the usual guideways of the holder. The depressed portion B, with the character for indicating the plate-holder, registers with an aperture A formed in the removable portion of the back A said aperture being covered by a translucent pane Q of a color to prevent the sensitive plates or films from becoming lightstruck. By the arrangement described the operator can see at any time the character on the depressed portion of the plate-holder last exposed, and thus can keep a record of the pictures taken. Each plate-holder is provided in its back near the entrance end for the plate with a lug B to spring against the outer edge of the plate to hold the latter sccurelyin the holder. (See Figs. 4 and 13.)

In using the device the operator fills the box A with the plate or film'holders I) in a dark room through the back AZof which the removable portion or cover A has been removed fer the purpose. The forward plateholder B rests against the cut'out portion of the front of the lining, and the rear plateholder is pressed on by the spring E to hold the several plate-holders firmly against one another. When the back is closed, then the box is ready to be used in the camera and is inserted therein in the usual way and fastened thereto, and when it is desired to make an exposure thenv theoperator pulls out the slide .C ,-ajnd,in ,doing sofrhe strip H with the plate H, mov es forwardly to bring said strip lliagainstthe fixed part A of the front A and renderthe box light-proof. When the exposure has/been made, the operator pulls the removing-barb) outward to cause the lug F. to push the. front plate-holder, with the ex posed plate or film, into the bag D, the outer end of which is now taken hold of by the operator and moved to the outer edge of the plate-holder to grip the same between the strengthening-strips D' The operator now by extending the bag pulls the plate-holder completely out of the slot A so that the free end of said plate-holder is outside of the side A between the top A and the bottom A thus enabling the operator to swing the plateholder rearwardly and bring it into alinement with the slot A and to then push said plateholder into position in the back of the box under the spring E and cause aforward movement of all the plate-holders by the action of said spring against the back plate-holder. The plate or film in the front plate-holder can now be exposed, and the above-described operation is then repeated.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A magazine plate holder for photographic cameras, provided with a box for containingthe plate or film holders, and arranged at one side for the removal of the exposed front plate-holder and for the return of said plate-holder to the back of the box, a bag attached to the box, the mouth of the bag opening on said side of the box, to permit the operator to take hold of and handle the exposed plate or film holder, 011 removing the same from the front and storing it at the back of the box, without exposure to light, a slide fitted to move in the front of said casing, and a spring-pressed plate covered with a strip of soft material and carrying one side of the mouth of the bag, said strip normally resting against the slide, and upon withdrawal of the latter, resting against the fixed portion of the box, substantially as shown and described.
